A novel chromene compound is, for example, represented by the following formula, and in which, as a basic structure, a condensed ring having a particular divalent group bonded to carbon atoms at the fourth and fifth positions of a fluoreno group is spiro-bonded to the first position of an indene ring, a particular divalent group is bonded to carbon atoms at the fifth and sixth positions of a chromene ring to form a condensed ring, and particular substituents are bonded to a carbon atom at the second position of the chromene ring.Type: GrantFiled: May 18, 2000Date of Patent: January 22, 2002Assignee: Tokuyama CorporationInventors: Junji Momoda, Yuichiro Kawabata

Patent number: 6331625Abstract: Photochromic spirofluorenopyran compounds corresponding to the general formula (I): in which B, B′, R1 to R4 and G have the meanings defined herein. The compounds of the invention are useful in the production of photochromic articles, particularly articles made of synthetic resin materials, and exhibit rapid darkening and brightening rates, as well as long useful service lives. By appropriate selection of substituents, it is possible to adjust the properties of the compounds such as absorption maxima (color), brightening rate, etc.Type: GrantFiled: April 25, 2000Date of Patent: December 18, 2001Assignee: Optische Werke G. RodenstockInventors: Claudia Mann, Udo Weigand, Manfred Melzig

Patent number: 6296785Abstract: Described are novel photochromic indeno-fused naphthopyran compounds, examples of which include naphthopyran compounds having a substituted or unsubstituted indeno group, the 2,1 positions of which are fused to the naphtho portion of the naphthopyran as shown below. Also present on the naphthopyran are moderate to strong electron donor substituents at the number 6- and 7-positions and optionally at the 8-position of the pyran ring or a cyclic group fused to the h side of the naphtho portion and weak to moderate electron donor substiuents at the 3-position of the pyran ring. Certain substituents may also be present at the number 5, 8, 9, 10, 11, 12, or 13 carbon atoms of the compounds. These compounds have a rating of at least 80 in the Relative &Dgr;OD at Saturation Test and may be represented by the following graphic formula: Also described are polymeric organic host materials that contain or that are coated with such compounds.Type: GrantFiled: September 6, 2000Date of Patent: October 2, 2001Assignee: PPG Industries Ohio, Inc.Inventors: Clara M. Nelson, Anu Chopra, Olga G. Petrovskaia, David B. Knowles, Barry Van Gemert, Anil Kumar

Patent number: 6255324Abstract: 5′-substituted, 4′,5′-dihydropsoralen compounds (5) bearing tertiary amines (and salts thereof), quaternary ammonium moieties or organomercurial moieties are described. Also described are 2-substituted mercurimethyl-2-3-dihydro-benzofurans of forumla (7): Also reported are versatile direct syntheses through a hitherto unknown compounds such as 3-R-4,8-dimethyl-4′,5′-dihydro-5′-bromomethylpsoralen or a 3-R-4,8-dimethyl-4′, 5′-dihydro-5′-iodomethylpsoralen to prepare a structurally diverse array of partially reduced psoralens and benzofurans. The presence of a permanent ammonium charge in these psoralens precludes membrane passage and the mono-unsaturation precludes the cross-linking of nuclear DNA, thereby minimizing the mutagenic/carcinogenic side effects long associated with psoralen-derived therapies.Type: GrantFiled: November 25, 1998Date of Patent: July 3, 2001Inventors: Ned D. Heindel, Jeffrey D. Laskin, Diane E. Heck, Robert D. Rapp, Marilyn S. Whittemore, Thomas E. McNeel, Ivan Jabin

Patent number: 6177424Abstract: The invention relates to 4′-substituted-4′,5′-dihydropsoralen compounds of formula(V): In the formula R is hydrogen, a halogen, CN or an acyl group; T is a halogen, CN, a carboalkoxy group NR1R2, or (N+R1R2R3)X−, R1 and R2 are independently a C1-C6 alkyl, or R1 and R2 together with the nitrogen form a 5-8 member heterocyclic ring, or when T is (N+R1R2R3)X−, R1 and R2 together with the nitrogen form a 5-8 member heterocyclic ring or heterocyclic aromatic ring; R3 is hydrogen, a C1-C12 alkyl, or, when R1 and R2 together with the nitrogen form a heterocyclic aromatic ring, R3 is a double bond within the heterocyclic aromatic ring; X− is a halide. In another embodiment, the invention relates to processes for preparing 4′-substituted-4′,5′-dihydropsoralen compounds described above.Type: GrantFiled: November 30, 1999Date of Patent: January 23, 2001Inventors: Ned D.

Patent number: 6162931Abstract: The family of dyes of the invention are fluoresceins and rhodols that are directly substituted on one or more aromatic carbons by fluorine. These fluorine-substituted fluorescent dyes possess greater photostability and have lower sensitivity to pH changes in the physiological range of 6-8 than do non-fluorinated dyes, exhibit less quenching when conjugated to a substance, and possess additional advantages. The dyes of the invention are useful as detectable tracers and for preparing conjugates of organic and inorganic substances.Type: GrantFiled: April 12, 1996Date of Patent: December 19, 2000Assignee: Molecular Probes, Inc.Inventors: Kyle R.
